I would be very cautious about using that quantity of sulfur. It is fungicidal and can cause nutrient excesses of elements such as iron as it oxidizes to sulfate. I would not consider your soil pH as too high compared to most of the drier portions of the western US. What is the sulfate-sulfur level on a soil test? Too much interferes with other anions.

Is any one running on the high side of pH, I am sitting between 6.9-7.4 in my different locations. I run 6-10 soil tests a year and over the last 4 years I have been able to lower my pH .2 to .5 points. These are in hoops and outside. I had sulfur spring and fall. 1-1.5 pounds per 100 square feet.

I am not up on cover crops, but could planting a certain kind help with lowering my pH?

Also, my P and K counts are off the charts. My whole "farm" use to be outside hog lots for many years. They were tore out in the late '90's. I just add some N and small amounts of P and K, concerned that even though they are very high, that some of it won't be usable for the plants...

I think the high P and K helps to bring out flavor in my tomatoes. I always get comments about how good they taste.

Just curious to see if anyone out there is dealing with similar situations.

Thanks,

Jay
